HELCOM RED LIST Biotope Expert Team
Baltic photic bottoms with at least 90 % coverage of sand. Sand has less than 20 % of mud/silt/clay fraction (<63 µm), and the proportion of sand (grain size 0.063–2 mm) exceeds 70% of the combined gravel and sand fraction. No macrovegetation or epibenthic macrofauna. Biomass of infaunal polychaetes dominates in the group that includes infaunal bivalves/polychaetes/crustaceans/insect larvae.
Substrate is sand. Appears in high energy exposure areas.
Pygospio elegans, Marenzelleria spp., Hediste diversicolor, Ophelia spp. and Travisia forbesii
